History:
(Avengers I#358 (fb)) - The world of Polemachus faced an unprecedented danger
when the energy rings that gave the world life began to flare out of
control. In desperation, the masses, led by a priest named Anskar, turned to the
ancient ways of Polemachus for an answer, and decided to appease the gods
through a human sacrifice. All of the daughters of the noble families were
gathered, and Astra was chosen to be sacrificed to the gods. Astra believed in
her duty and believed in the gods, and was willing to be sacrificed. However,
Thundra and Arkon, the rulers of Polemachus saw the act of human sacrifices as
incredibly immoral. The night before the sacrifice was to be carried out,
Thundra and Arkon stormed the holy prison where Astra was being kept, convinced
her that her self sacrifice would not save their world, took her, and fled
to Earth.

(Avengers I#358) - Once on Earth, Arkon, Thundra, and Astra
were confronted by the police as well as the people of New York, and Arkon attempted
to scare them off by destroying some property around them. However, the Avengers
showed up and before too long, Arkon, Thundra, and Astra explained that they had
come to Earth to avoid the human sacrifice of Astra. But just as they finished
telling their story, Astra, along with Arkon, Thundra, and the Avengers, were
teleported back to Polemachus by Anskar, the priest who wanted Astra's death.
Anskar tried to persuade Arkon into killing Astra, telling him it was the only
way to quiet the wrath of the gods and the cries of the people. Astra was once
again willing to give up her life if Arkon willed it, but the Vision managed to
convince Anskar and Arkon to give them twenty-four hours to try and fix the problems with
the energy rings.

(Avengers I#359) - Astra was present as the Avengers
formulated their plan to leech some of the excess power off of the energy rings,
but with only twelve hours left, Astra began to feel very nervous and anxious.
Eventually, the Avengers were successful in their ploy and returned to
Polemachus after restoring it. Astra ran up and hugged Arkon in joy, only to be
stabbed in the back and killed by Anskar, whom insisted that the Avengers only
succeeded with help from the gods, who still needed their gift.
